Title: Case Hierarchy based representations and procedures for domain analysis and the construction and porting of natural language interfaces

Abstract: Natural language interfaces must take advantage of as many types of constraints as are available in order to provide efficient and unambiguous language processing. An important source of constraints is provided from the specific domain for which the interface is built. However, the process of porting an interface built for one domain to a new domain has not been well defined, and is a difficult one. Many natural language interfaces are based on case grammar. However, there is little agreement between theories of case grammar and different natural language processing systems that use case grammar concerning the number and types of cases that are needed.

This research provides a solution to the problems of the disagreements concerning the cases themselves, and the difficulty of porting an interface that has been tailored for one domain to another domain. A Case Hierarchy was developed to represent cases as they exist in the abstract, or for "general natural language," and as they are actually used in a particular domain. The cases used in the Case Hierarchy were tested for coverage on a large collection of sentences from the Wood Corpus. The Hierarchy was used as the basis for a domain analysis procedure that determines the cases that are required in a domain, and the words that can use each case in their case frames, or that can act as fillers for the case. A software tool was then built that embodies the Case Hierarchy theory and domain analysis procedures in a set of intelligent editors that guide the user through the domain analysis process. A feasibility study of the Case Hierarchy theory and Tool was performed.
